The first Devastator was Soviet officer, spy, and saboteur Kirov Petrovna, who wore powered armor designed by the Gremlin.
This full body armor is equipped with electronic devices which absorb microwave energy and can convert it for use as blasts of heat or concussive force.
Its solar powered boot jets enable the wearer to fly at just under Mach 1, with range limited only by available light plus a three-hour battery reserve.
Because the battle-suit draws power from microwave energy beamed down from a satellite located in geosynchronous orbit, the suit's wearer must maintain a line-of-sight position relative to the satellite to avoid sudden power cut-off.
The satellite itself was protected by ECMs which rendered it invisible to conventional modes of detection.
